Stephanie Zapata Moore, who serves as Executive Vice President and General Counsel at Vistra Corp (NYSE: VST), disposed of 10,000 shares of the company’s common stock on March 9, 2026, according to a Form 4 filed with the Securities and Exchange Commission. The shares changed hands at a weighted-average price of $160.31, producing proceeds of $1,603,100. Reported execution prices for the individual trades ranged between $160.00 and $160.70.
Following this sale, Moore retained direct ownership of 114,409 shares of Vistra. The filing notes the transaction was carried out under a trading arrangement compliant with Rule 10b5-1, a plan Moore established on December 2, 2025.
Market metrics cited alongside the filing place Vistra at a price-to-earnings ratio of 71.84, with analysis from InvestingPro indicating the stock appears overvalued at current levels. The company has nonetheless produced a meaningful 31% total return over the trailing 12 months.
The insider sale arrives amid a set of quarterly results that blended shortfalls and positives. In fourth-quarter 2025 results, Vistra reported earnings per share of $2.13, missing the $2.33 forecast and producing an EPS surprise of -8.58%. Revenue for the period came in at $4.58 billion, below the projected $5.3 billion and registering a revenue surprise of -13.58%.
Despite those misses, certain operational metrics exceeded expectations. Vistra disclosed adjusted EBITDA of $1,742 million for the quarter, a figure that surpassed both an individual firm estimate and the consensus forecast referenced in coverage. Analysts commenting on the company maintained generally constructive stances: Scotiabank retained a Sector Outperform rating for Vistra, and BMO Capital adjusted its price target upward to $241.00 from $240.00, citing the company’s financial flexibility.
Management reiterated guidance for both EBITDA and free cash flow for 2026, according to the company commentary included with the results. Market observers and analytics similarly highlighted Vistra’s aggressive share buyback activity as a material element of the company’s capital allocation strategy; InvestingPro lists additional tips and analysis related to that program.
Context and implications
The transaction recorded in the SEC filing was executed under an established 10b5-1 plan, which typically reflects a pre-planned schedule of trades and is intended to insulate the holder from allegations of trading on material nonpublic information. The sale’s timing coincides with a mixed earnings backdrop: bottom-line and top-line misses but an adjusted EBITDA beat and sustained share repurchases.
Investors should note that the company’s valuation metrics and recent performance produce a layered picture: a strong one-year return paired with a high P/E ratio and the recent quarterly revenue and EPS shortfalls.
